CAN-HEADING iuacnmn.

Application filed December 81, 1926. Serial No. 158,283.-

The present invention relates to a machine adapted for heading non-circular cans or can bodies of the type wherein the seaming rolls revolve around the stationary'mandrel holding the can end and are conformed in a manner complementary to the shape of the can, so that as they roll around it they turn and set the seam- The machine is applicable for bottomingecanbodies or for topping filled cans.-

The object of the invention is to improve upon the machines of this type, to render the revolving head more compact, to enable the speed of rotation, and therefore the output of the machine, to be increased, to rovide for better lubrication than hereto ore, and in other ways to perfect the operation of the can head seaming elements.

The macnme in general is of a well-known type, ofmachine having a suitable fixed frame which includes a bracket arm or horizontal extension A at the top, this being the only portion of the machine frame which is shown in the drawings. Thisarm forms the bearing support for drive shaft B, by which the working elements are rotated. In the fixed arm A is fastened a stationary shaft or spindle C which carries at its bottom end a stationary mandrel D, forming as usual the upper member of the can-holding chuck. Around the fixed spindle C is mounted the hub portion of a revolving head E. To the top of this head is fastened a bevel gear F which meshes with a bevel pinion F on the drive shaft B wherefrom the head' E is driven.

The head E, which is shown as a single casting, comprises an upper flange E, a middle tubular hub portion e, and 'a lower plate or disk 7, the latter being formed as a preferably flat plate having openings f f on opposite sides, as shown in Fig. 11. In these openings move slides G G, one of which is shown separately in Figs. 12 and 13. Each of these slides has a vertical opening 9 with plate deparallel sides serving to receive a carrier H which is'clamped fast to the slide G; the carriers H H carry the spindles I I of the seaming rolls or seamers J J. These seamers are conformed as shown in Fig. 5, so that their exterior contours are complements to the form of the mandrel D; that is, where the mandrel is an unequal sided vquadrilateral with rounded corners (as shown in dotted lines in Fig. 5), the seamers are so shaped that as they rotate in engagement with the mandrel they bear equally against it at all portions of its perimeter, being formed with hollows entered by the salient portions of the mandrel, and with projecting curved ortions engaging thefiat sides of the man rel. In the construction shown, this conformation is that peculiar to a gearing in the ratio of 2 to 3, so that for the two long flat sides of the mandrel there are provided on each seamer three major projections, and between these are minor projections corresponding to the shorter flat ends of the mandrel, and between the major and minor projections are hollows or concavities conforming to the four roundedcorners of the mandrel.

In a machine of this type it is necessary that the seamers be revolved on their axes in agiven gearing ratio to the mandrel (in this case 3 to 2) that they be movable toward and from the mandrel, so that first one and then the other may act upon the can head to seam it down, and that they be so geared that when retracted out of action they will continue to revolve in perfect step so as to properly mesh when brought into action; and that their respective movements be so timed that the first seamer will be first advanced into working engagement with the can head, and after performing its part of the work of seaming; shall be retracted,-

and then the second seamer be advanced and held in engagement until its work is performed, and then retracted. The means for performing these functions will now be described.

-Rotatz'ng the :seamers.I-Ieretofore such seamers have been mounted on the lower ends of upright shafts hung pendulously at their upper ends and there provided with planet gears revolving around a sun gear on the stationary central spindle; and provided with means for swinging their lower ends radially to bring one seamer or the other into or out of action. According to the present construction the seamer' spindles I I 'are mounted vertically to have a parallel i had a swinging movement. To provide for seamer gears M M.

head E carries the seamer spindles I around,

this new mounting and movement the present invention introduces a difl'erent form of gearing for driving the seamers.

A stationary or sun gear K is carried by the stationary spindle C at its lower end and preferably just above the mandrel D. In continuous mesh with this are.two planet gears L L, and directly below these are two As the rotation of the the gears L L-roll around in mesh with the sun gear K and consequently are rotated 1n the determined ratio; their rotation is communicated through a coupling device to the gears M M respectively, so that the latter revolve in perfect timing with the gears L L (each having the same number of teeth). Thus, when the gears M or M are by the movement of the slides H carried away from the mandrel, so that they are brought out of mesh with the gear K, they are nevertheless kept 1n rotat on at the same speed through the intermediation of the coupling. The gears L L are kept in mesh 'with the gear K by having a hub portion 12 which revolves within an annular bearin 13 formed 'in a plate Z called an outboard bearing) which is fastene beneath the disk) (see Fig. 9). The gear L has an opening 14 (Fig. 7) amply large to provide for the radial movement of the spindle I which passes through it. together by a coupling N shown in Fig. 8,

The gears L and M or M areicoupled' consisting of a ring having lower arms 15 :which enter notches 16 (Fig. 7) in the gear L, and upper arms 17 which engage notches 18 in a. flange 19 formedon thefspindle, I

(Figs. 5, 6 and 9). The respective arms are.

arranged at right angles to each other an diametrically of-the' ring, and have paralle sides, so that they may slide in the respective notches 16 and 18; consequently they can adapt themselves to the eccentricity due to the movements of-the spindles toward and from the center of rotation. Thus rotation is communicated from the gears L to the spindles I, and as the gears M M are ke ed on the lower ends of these spindles, these atter gears are driven in exact timing with the gears L L. The seamers J J are fastened in non-rotative manner to the gears M M (or otherwise to the spindles) as by bolts 20.

The spindles I I are provided with suitably prolonged bearing bushings 7:. within the carriers H, and are desirably made ho1-' low in. order to receive grease or other lubricant. Oil holes 21 (Fig. 6) are provided for admitting the lubricant to the coupling N.

,The splndle carriers H are essentiallya part of the slides G, since they are clamped are, however, adjustable radially with reference to the slides, so that the spindles I I may be set to different distances from the central axis of rotation. The purpose of this is to-provide for the initial adjustment of the machine and its readjustment incident to the changing of the seamers J J and mandrel D to adapt the machine for different sizes or shapes of cans. To enable the carriers H to be clamped-fast to the slides G, they are made in two' parts; the bushing h is housed in a tubular standard 2' projecting from a-square or flat-sided body j beneath; this portion y has a shoulder 22 which fits beneath a shoulder 23 (Fig. 13) in the slide G so as to resist upward-movement: above the body portion y is a cap por-.

tion k having a recess which engages over the tubular portion 5, and its bottom resting 110 fast to the slides and move with them. They v on top of the slide G, as shown at the left in Fig. 6; thus the slide G may be clamped between 'the cap portion k and the shoulder 22; to perform this clamping, a ring or nut 23 is screwed down upon a threaded upper portion of the tubular member 2'. By set ting back the nut '23 the parts are so released that the carrier H may be slid radially within the opening 9 in the slide G, and by proper adjustment may be set fast there-in by screwing down the ring or nut 23. 1

Sea/mar ti/mz'ng meckam'sm.-As stated, the seamer J is first moved radially inward to turn the seam, and is then moved outward to release it, while at the same time or instantly thereafter the seamer J is moved in to set and finish the seam, after .which it is moved outward to release the can and permit it to be fed away. The means for accomplishin these movements of the seamers (common y called the timing mechanism) will now be described.

On the stationary spindle C is keyed fast (see Fig. 4) a gearP (shown in plan in Fig. 2); this serves as a ,sun gear around which revolve two planet gears Q Q fastened on verticalshafts R R carried by the head 1*] (see Fig. 4). These shafts R have suitable u per and lower bearings in the members of the head, and between these bearings are formed with worms S; each worm meshes with two worm wheels T T between which it is located; two of these worm wheels are fastened on a shaft U, and the other two on a shaft U.

ries a pair of timing cams V V for the primary seamer J; the shaft U carries a pair the cam face of the cam V or V. Each lever m has on the under side of its hub a toothed sector constituting a partial pinion, all this being best shown in 'Fig. 1. These pinions 12 mesh with racks g which are fastened in recesses in the face of the lower plate or disk 7 of the head. Thus as either cam V or V presses down the roller 24 of either lever m, the pinion teeth 1 of such lever execute a rolling movement in enga e-' ment with the teeth of the rack q, where y the lever axis (on the pin n) crawls or- ,floats toward the center of rotation of the head; since the pin a is held in the ears 25 of the slide G, this moves the slide radially toward the center, carrying with 1t the carrier H, spindle I, and seamer J or J. Thus the seamers are moved toward the The shaft U car- The two pairs of cams are ar-.

mandrel D as the rollers areencountered by the salient portions of the cams V V, and as the rollers drop into the hollows of these cams the springs 26, pressing up the rollers, cause a reverse movement of the floating levers m'and consequently an outward sliding movement of the slides G G and their appurtenant parts. The movements are determined by the peripheral conformations of the cams V V, which are shaped as shown in Fig. 1, so as to accomplish the required succession of inward and outward movements of the respective seamers. These movements being well understood in the art, it

is unnecessary to make a precise showing of the cam conformations or to precisely describe the successive movements of the seamers. It will be'observed that the levers m m, being connected by their pins n, and arranged in pairs under the respective pairs of cams, have precisely like movements and thereby impart precisely parallel thrusts in radial directions to the slides G G. Thus the movements are as nearly frictionless as possible, and'by reason of the rolling action of the pinions p (which act as the short arms portion to the rotation of the head, so that,

each seamer, after advancing to its work, will remain m'actlve contact with the can .head long enough to accomplish the seaming. The pins n are reduced attheir ends, and these reduced portions overhang slide plates 27 fixed on the plate F of the head (see Fig. 9), which slide plates engage the.

margins 28 of the slides G. These reduced and overhanging end portions of the pins serve as stops to prevent. rotarymovemen of the pins n as the levers m turn.

The seamers are backed against springs, so that they may yield while rolling down the seam and avoid crushing or injuring the metal. ,These springs W W are shown in Figs. 1, 4 and 9'. They act to press down thecam shafts U U and allow these shafts to yield upwardly in case excessive/pressure is transmitted from the cam C through either seamer, its slide G and levers m to the corresponding cam tending to lift it. The springs W, instead of pressing directly down'upon the shafts of the bearings U U,

are shown as arrangedto bear down upon the free ends of levers r 1, each of which is pivoted on a pin 1" hung in a bearing framewhich is fastened down to the plate The result is a very smooth and the recess in the mandrel.

To prevent any possible rotation of plates 60 detached- An important advantageof this machine is that the seamers, in moving toward and from the mandrel, have a straight line movement in an unvarying plane. Heretofore they have been swung from rocking centers intersecting the axes of theseamer spindles and at a pointconsiderably above;

this causes the seaming edges to move in an occasioned practical difliculty because of bringing the seaming surfaces out of theare while approaching toward or receding from the mandrel. This are movement has horizontal plane of the seam. To diminish this disadvantage as much as possible the points of pivotal support above have been carried up as high as was possible, which again involved another disadvantage, namely, that the revolving head was made unduly high, thus adding to the height and weight of the entire machine and requiring a longer pro ect1ng portion of the stationary central spindle, which necessitated making this undesirably large and heavy to give it proper rigidity. By mounting the seamer spindles in slides which have a horizontal rectilinear movement the seamers are caused to move in a true horizontal plane without any vertical component of motion; it results from this that the seamers approach to and recede from the mandrel in such way as to correctly engage the flanges to be seamed, and without any liability of making a distorted seam illustrated and described, which, may be varied within the scope of the appended claims and in accordance with the requirements of the machine. The illustrated machine is designed for heading filled cans which cannot be revolved without disturb ing their contents; for heading empty cans,

the mandrel holding the can may revolve,

the operative relation of the parts in other respects being unchanged.
